摘要：

The sequential electrodeposition of Pt nanoparticles and CeO2 protective layers has been explored as a simple method to prepare structured catalytic reactors characterized by a core-shell metal-metal oxide active phase directly anchored onto metallic (Fecralloy) 3D open foam substrates. The application of a CeO2 overlayer onto preformed Pt nanoparticles promoted the intrinsic catalytic activity for CO oxidation and induced a remarkable stabilization effect against sintering and extensive reconstruction of the active phase up to 800 degrees C.
